Kernel Panic debug
I'm getting a Kernel panic error.
My partition info:
(internal scsi drive - contains GRUB in the /mbr)
sda1 XP 2gb repair
sda2 XP 250gb main
sda3 XP 3gb support
(external usb scsi drive - where mepis linux is installed)
sdb1 25gb ext3 /
sdb2 20gb ext3 /home
sdb3 8gb ext3 /tmp
sdb4 3gb linswap /swap
Grub boot screen:
MEPIS at sdb1, kernel 2.6.12
Windows at sda2
MEMTEST
XP boots fine on the internal drive.
MEMTEST ran 21 times with no errors.
Booting Linux from the external usb drive I get the following error:
"Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block (0,0)"
I changed my GRUB kernel line to this:
kernel (hd1,0)/boot/vmlinuz-2.6.12 single debug 3 confirm
5 pages of output later, I received 4 errors right before it stopped. Here are those last few lines of output starting with the first error:
RAMDISK: Couldn't find valid RAM disk image starting at 0.
usb 1-2: new high speed USB device using ehci_hcd and address 2
FAT: codepage cp437 not found
FAT: codepage cp437 not found
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(8,3)
<3>usb 1-2: device descriptor read/64, error -71
Any ideas? Thanks for the help.
Here's two other files if interested:
